6 things Obama must do at the Democratic National Convention

Many American voters will view the 2012 election as a referendum on the Obama presidency, so party leaders need to be ready with their defense. Here are six things Democrats and Obama can do at the Democratic National Convention in Charlotte, N.C. this week if they want to secure victory over Mitt Romney and the GOP in November.

2. Set a positive tone for a positive future

Obama first captured national attention with his keynote speech at the 2004 Democratic convention. He told his remarkable life story and called the nation to unity, defusing critics with lines such as: "I say to them tonight, there's not a liberal America and a conservative America – there's the United States of America." This convention offers him yet another chance to dazzle a national audience with a positive message.

Hope and change worked in 2008 because most voters said they wanted something new. But now the president is asking for four more years, so he needs to chart a clear, positive plan for what he will accomplish ahead.
